Injecting Test testosterone cypionate/testosterone enanthate sub-q has become a preferred method of administering Test in the TRT/HRT world when doing shots with 1/2cc or less.
I do sub-q injects with a 27gx1/2 needle and I find it hard as hell to push the plunger even with warming up the syringe. That said, I know that some guys are using 29g needles.
